Description

Height pruning platform with leveling automatic

The present specification refers to, as its title indicates, to a platform to prune in height with automatic leveling, of the type used in both areas with sloping streets for pruning and conservation in gardens and parks as in agricultural areas for tree pruning, designed to perform pruning work on land up to 20% drop, saving steps up to 0.5 m. approximately.

Automatic leveling consists of some tilting supports replacing the traction axis, are located in the ends of the chassis, one on each side and in an inverted position, housing the reducers with their corresponding faces wheels, and on its inner face a hydraulic cylinder, which as they are ground conditions, leveling the machine up or lowering the hydraulic cylinder rod.

The elements that make up the leveling automatic are located inside the chassis, a automaton, governing the end of the cylinder race hydraulic, electro valves and piloted valves to interlock the Hydraulic cylinder stem position and an inclinometer programmable, which regulates the inclination of the chassis.

It is very important to maintain the chassis level to perform the work safely, and to save the orographic difficulties of the terrain, the chassis can take a maximum inclination of 3º, after having exceeded the ranges of working of the machine, at that precise moment the inclinometer programmable sounds an alarm to notify the user that it is working within the maximum safety limits. In the case of exceed this maximum inclination of 3º, the inclinometer is programmed so that when the inclination reaches 4º, the Machine stop automatically. This allows the user can rectify your position with total security and be able to continue With your work.

The same owner owns a platform Pruning foot in protected height on the Utility model U200302634 with some concrete constructive peculiarities like a rolling base, self-propelled and directional equipped with safety elements, shaft rear with tracks or on wheels, articulated and swivel arm with two sections that incorporate a basket from which it is controlled and directs the platform all controlled and regulated by elements Security and alarms.

There are currently major problems for perform pruning work on land with a very orography irregular, or on uneven surfaces of certain consideration that may jeopardize user safety. In these cases it is difficult to access these lands, always with very careful, trying to pave the ground or fit the machine or using other resources not always safe and high risk to the user, in addition to the budget increases that these impediments can suppose.

To solve the problem in the The platform for pruning in height has been devised with automatic leveling which has an optimal constitution, a reduced size, and is self-propelled and handled from the basket, what which allows the operator located there at all times be placed in the optimal place to perform pruning. Also also incorporates pressurized air intakes for the coupling of pneumatic tools, such as pruners, in it basket.

According to the invention, the platform is constituted by a self-propelled and directional rolling base, to base profiles and sheet metal, can be done in two different versions depending on the constitution of the platform, with automatic leveling on the rear axle or with leveling Automatic on both axes.

For its self-propelled base, it incorporates an engine of explosion and a preferably hydraulic transmission to a shaft rear, also having a front axle, whose axes can put on caterpillars, preferably rubber or they can mount wheels.

The incorporation of a track system, preferably rubber, on the height pruning platform, it is necessary when working conditions so advise, because gives more traction in unfavorable situations, in addition to increase the weight of the platform offers more security by the center of gravity shifted down.

At the base an articulated lifting arm is fixed of two sections, both driven by hydraulic pistons, and also rotatably by the action of another piston. At free end of the arm is fixed by a parallelogram a basket for the operator The controls are arranged in the basket, preferably electric, for remote platform handling, both of the rolling and directionality of the base and of the arm lift and turn. The piston drive and Hydraulic transmission is produced by the corresponding central oleodynamics driven by the explosion engine.

Also, an explosion is coupled to a compressor for supply of pressurized air to the sockets of the basket.

The height pruning platform is equipped with important security elements, such as an automaton that governs automatic leveling, programmable inclinometer connected to an alarm, located at the base, electro valves, limit switches, in addition to anti-slip and roll-over measures, such as parachute valves located in the fittings of the pistons, as required by directive 98/37 / CE.

The height pruning platform that presents brings multiple advantages over the devices currently available, the most important being its high effectiveness, because thanks to the automatic leveling of its axes It allows you to perform your own pruning work on land with a very irregular orography or on land with significant slopes or steps that need to be saved to access the elements of pruning, always being within the safety limits that mark the European directive.

Another important advantage is that from the basket a Only one person can remotely manage the platform, both of the rolling and directionality of the base and of the arm lift and turn.

Another of the most important advantages to highlight is that the height pruning platform is equipped with measures of safety, such as a programmable inclinometer connected to an alarm governed by an automaton and anti-slip and roll-over measures.

Another important advantage is that the engine incorporates a compressor which supplies the sockets incorporated in the basket, pressurized air for tool coupling pneumatic

Another important advantage is that the rear axle it can go on tracks, preferably rubber, especially when the platform must perform pruning on sandy ground, muddy or inclined, facilitating work and providing Greater security and stability.

To better understand the purpose of this invention, an embodiment has been shown in the attached drawing preferential practice of it. In that plane:
